HMC1034LP6GE

v00.1211

CloCk Generator with FraCtional-n Pll

& inteGrated VCo, 125 - 3000 Mhz

General description

the HMC1034lP6Ge is a low-noise, wide-band clock generator IC with a fractional-n Phase locked loop (Pll) that

features an integrated Voltage Controlled oscillator (VCo). the device provides differential clock outputs between

125MHz and 3GHz range. the HMC1034lP6Ge features low noise Phase Detector (PD) and Delta-sigma modulator,

capable of operating at up to 100MHz, permit wider loop-bandwidths with excellent spectral performance.

the HMC1034lP6Ge features industry leading phase noise and jitter performance, across the operating range,

that enable it to improve link level jitter performance, Bit-error-rates (Ber) and eye diagram metrics. the superior

noise floor (<-165dBc/Hz) makes the HMC1034lP6Ge an ideal source for a variety of applications –such as clock

references for high speed data converters, physical layer devices (PHY), serializer/deserializer (serDes) circuits,

FPGAs and processors. the HMC1034lP6Ge can also be used as an lo for 10G/40G/100G optical modules and

transponders, as well as primary reference clock for 10G/40G/100G line cards, and for jitter attenuation and frequency

translation.

the differential output of the HMC1034lP6Ge includes a 2-bit output amplitude control which may be set via the

sPI serial programming interface, and an output Mute function. the Delta-sigma Modulator of the HMC1034lP6Ge

features Hittite’s exact Frequency Mode, which enables users to generate output frequencies with close to 0Hz

frequency error.

[3] this maximum phase detector frequency can only be achieved if the minimum n value is respected. eg. In the case of fractional feedback

mode, the maximum PFD rate = fvco/20 or 100 MHz, whichever is less.
